Police and forensic teams in Nice are trying to establish more information surrounding last night's attack. Here are ten things we know so far:

1. Some 84 people – including ten children - were killed when the 25-tonne truck zigzagged a full two kilometres along the seafront Promenade des Anglais as a fireworks display marking the French national day – Bastille Day - ended just after 10.30pm

2. The gunman at the wheel of a heavy truck which ploughed into a crowd celebrating Bastille Day in Nice was 31 year-old Mohamed Lahouaiej Bouhlel. He was Franco-Tunisian, born in Tunisia. He was known to police for common crimes, but he was not known to intelligence police.

3. The truck careered into families and friends listening to an orchestra or strolling above the beach towards the grand, century-old Hotel Negresco. Eyewitnesses said the driver swerved from side to side to kill as many people as possible as he drove for two kilometres.

4. 18 of the injured are in a critical condition. 50 of the injured are children, and it is feared that many may now be orphaned.

5. The attacker also opened fire before police shot him dead last night

6. There has been no claim of responsibility this morning. Police are trying to establish whether Mohamed Lahouaiej Bouhlel might have had any accomplices in Nice which has a reputation for Islamist activism. Nice, a city of 350,000, has seen dozens of its Muslim residents travel to Syria to fight, a path taken by previous Islamic State attackers in Europe.

7. Some 10,000 soldiers will be on patrol in France in a Sentinel operation and state of emergency – which began after Islamic State gunmen and suicide bombers killed 130 people in Paris in November – whch has been extended by three months in France. President Francois Hollande has also called up "operational reserves", those who have served in the past and will be brought in to help police, particularly at French borders.

8. Italy has announced it will boost controls at three road crossings into France and at the Ventimiglia train link between the two countries. Nice is 35 km from the Italian frontier.

9. German Chancellor Angela Merkel said Germany would stand by France's side in the "fight against terrorism".

"Germany stands in the fight against terrorism at France's side, united with many, many others. I am convinced that, despite all the difficulties, we shall win this fight."

10. Bastille Day marks the 1789 revolutionary storming of the Bastille prison in Paris as an attack on liberty by fanatics who despised human rights.
